| <p> |
| Configuring Boost.TR1 is no different to configuring any other part of Boost; |
| in the majority of cases you shouldn't actually need to do anything at all. |
| However, because Boost.TR1 will inject Boost components into namespace std::tr1 |
| it is more than usually sensitive to an incorrect configuration. |
| </p> |
| <p> |
| The intention is that <a href="../../../libs/config/index.html" target="_top">Boost.Config</a> |
| will automatically define the configuration macros used by this library, so |
| that if your standard library is set up to support TR1 (note that few are at |
| present) then this will be detected and Boost.TR1 will use your standard library |
| versions of these components rather than the Boost ones. |
| </p> |
| <p> |
| If you would prefer to use the Boost versions of the TR1 conponents rather |
| than your standard library, then either: include the Boost headers directly |
| </p> |
| <pre class="programlisting"><span class="preprocessor">#include</span> <span class="special"><</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">regex</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">></span> |
| |
| <span class="identifier">boost</span><span class="special">::</span><span class="identifier">regex</span> <span class="identifier">e</span><span class="special">(</span><span class="string">"myregex"</span><span class="special">);</span> <span class="comment">//etc |
| </span></pre> |
| <p> |
| Or else don't enable TR1 in your standard library: since TR1 is not part of |
| the current standard, there should be some option to disable it in your compiler |
| or standard library. |
| </p> |
| <p> |
| The configuration macros used by each TR1 component are documented in each |
| library section (and all together in the <a href="../../../libs/config/index.html" target="_top">Boost.Config</a> |
| documentation), but defining BOOST_HAS_TR1 will turn on native TR1 support |
| for everything (if your standard library has it), which can act as a convenient |
| shortcut. |

| does not currently enable gcc's native TR1 implementation as this is currently |
| in an early stage of development. However, you may choose to do so by defining |
| BOOST_HAS_GCC_TR1. |
